This is 100 percent not true.You yourself may be able to lock your particular setup with controller set to 10 but thats not true on every setup.Weight of camper being an example amongst other variables.Yes when I had travel trailers weighing less then 8k I could lock my brakes up if my controller was set to ten.Moving to a fifth weighing 12-14 k not so much..Locking up your brakes has nothing to do with slowing down is the point here.In fact as said above will cause you to lose control.Not saying op doesnt have some kind of brake issue but locking brakes shouldnt be part of the equation in determining if they are working appropriately.

well this is right out of my prodigy manuel, they make the controllers and prob know more then me

Adjusting the Power to the Trailer
Brakes
(Prior to setting Boost)

Once the control has been securely mounted in the
direction of travel, it is necessary to set the power
needed to stop the trailer during a braking event.
1. Connect trailer to tow vehicle.
2. With engine running hold manual full left and set
Power Knob to indicate approximately 6.0
3. Drive tow vehicle and trailer on a dry level paved
surface at 25 mph and fully apply manual knob.
3
If trailer brakes lock up:

q
Turn power down using power knob.

3
If braking was not sufficient:

q
Turn power up using power knob.
4. Repeat Step (3) until power has been set to a point
just below wheel lock up or at a sufficient force as

to achieve maximum braking power.

Uhh... The second sentence of your contradicts your first one... I tend to believe that if a trailer of ANY given weight is setup with adequate sized brakes for the weight it should be able to lock the trailer brakes! If you are able to lock the tires in a braking maneuver that means you are achieving MAXIMUM braking force.

I, nor is anyone else stating that you should leave it set to lock the brakes when you apply the TV brakes, BUT I feel that you should be able to.

Worst case scenario I want to know that I have MAXIMUM braking force available to me and I can stop before I hit something, go over something ect ect...

What kind of braking force are you getting with locked drums?
Once the rubber starts to skid; there is zero braking going on.

Just before lockup at 25 MPH or so, is the correct setting. At speed, you should "just" feel the camper "tugging" on the truck when braking.

I am stating that you are ABLE to achieve maximum braking force if you are able to lock up. You are correct that true maximum force would be just shy of locking the tires. Hence anti lock brakes. But I still believe that a properly equipped trailer will be able to lock the tires.

nobody including me thinks that they should drive around with the controller set to lock the brakes but I think I ought to have the available power to do it. my issue is with the brakes adjusted to just drag and with the controller set to max is still does not stop very well.

I think some of the disconnect is how the electric brakes work compared to the hydro-mechanical brakes on a car or truck.

The electrical signal from the controller goes to a magnet that tries to grab the drum. the sliding of the magnet on the drum activates an arm that applies the brake. It is very hard to lock the drum at most any speed since the magnetic force required to stop the drum rotating would be quite high.

With an adequate brake setup you SHOULD be able to lock the drum/wheel... Adequate being the key word and open to interpretation from different individuals...

IMO, the speed would have to be very low and the voltage (bias) setting very high to do that.

yes, hence the 25mph speed that the adjustment is made
